Обсуждение: Corrupted Dabatabase

The issue sounds more like your server than just Postgres - search the
net for "read only file system" for your OS.

Hello Everydody, 

 My database is corrupted, each time i try to list all the tables in the database  i have got the following message

hla2db=> \d

ERROR:  could not open relation 1663/16385/1255: Read-only file system

I read that my best option is to use my backup. Before using my backup i would like to remove all databases in postgresql and create everything again from scratch. Unfortunatlly i can't see the list of databases, althought i am able to create databse

 can you suggest what to do? is it a good idea to reinstall postgresql?

May be you filesystem is mounted read-only after power loss or some OS crash?

What OS do you have   - WIndows or some kind of Unix (Linux,  etc). Also what  file system  Postgresql data dir is using?

hi 

 

 thank you for your quick answer,

 

 

 I  am working with linux. here you have the output of uname --all

 

 

 

Linux XXX at 2.6.18-274.3.1.el5 #1 SMP Tue Sep 6 20:13:52 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

 

And the filesystem is ext3

 

 i was able to work with the database until last week when i was indexing the database. the problem came when i tried to cancel a \di command

 

 as far as i know nothing  changed since the last time  i was working last week.

How did you cancel the command?

Also elaborate on what you mean by 'indexing the database'?
